Overview

Peptide drug delivery has evolved from simple subcutaneous injections to sophisticated oral, nasal, and implantable systems.

Key Milestones

  • 1920s: Subcutaneous insulin injections
  • 1970s: Nasal peptide delivery explored
  • 1980s: Implantable peptide pumps
  • 1990s: PEGylation extends half-life
  • 2000s: Oral peptide delivery attempts
  • 2010s: Microneedle and nanoneedle systems
  • 2019: Oral semaglutide (Rybelsus) approved

Impact

Overcoming the delivery challenge remains the greatest obstacle to broader peptide therapeutic use. Oral semaglutide marked a breakthrough for oral peptides.
